Technical Analysis: What you Need to Know Before
you Look at a Chart?
Before you delve into the world
of double bottoms, head and shoulders, flags, triangles and wedges
you should first try to understand the background to technical
analysis (TA). By accomplishing this you can decide if this potentially
powerful tool is for you and how it could help guide your trading
and investment decisions.
What is Technical Analysis?
Technical analysis is the study of price data and statistical indicators that
are formed by market activity. Market activity illustrates the
flow of supply and demand. This supply and demand is a reflection
of beliefs and opinions translated into human behaviour and specifically,
herd mentality. Therefore, technical analysts would argue, price
patterns and indicator signals can be categorised based on historical
data with a reasonably high expectation that they will occur again
at some point in the future. This argument is based on the theory
that human behaviour is innate and, although it adapts and evolves
over a long enough period of time, it remains basically the same.
Technical analysts focus on the herd mentality and how it affects
the individual. It is after all very difficult to hold an opinion
contrary to popular consensus especially in an arena where you
have to make your opinions know, as you do in the financial markets
(in the form of trades).
A Little Bit of History Repeating
Mark Twain (the American humorist, writer and lecturer) once said
that “History doesn’t repeat itself-at best it sometimes
rhymes”. This is true for the subject of this article,
technical analysis. Although TA is based on using patterns that
have previously occurred to predict the moves of the future no
two patterns are ever exactly the same. How can they be when
you list the variables that determine price action: trading methodologies,
the number of participants, the participants themselves, order
sizes, market
liquidity, the list goes on. We all know that no two pairs
of eyes are ever the same but they are similar enough for you
to recognise which are blue or brown etc. The same can be said
for price patterns and indicator readings; no two are ever exactly
the same but they are similar enough that they can be classified
and you can draw a prediction as to where prices are likely to
move on completion.
Self-Fulfilling Prophecy
One of the major debates surrounding technical analysis is that
it is self-fulfilling. Therefore if enough people use TA and
trade the set-ups then they will influence the move they endeavoured
to predict in the first place, thus harming its effectiveness.
It doesn’t really matter which side of the fence you sit
on here, the fact is that a degree of self-fulfilment is inevitable
but it doesn’t necessarily guarantee the success or failure
of the method. If a price pattern emerges it is not as though
every technical trader defines exactly the same entry point and
pulls the trigger at exactly the same time or the market would
not function. Price would jump instantaneously causing massive
slippage and partial fills and then collapse as traders took
their profits. The opposite of this would of course be true if
technical analysis was deemed as a poor method of analysis. In
reality we find ourselves at a happy medium. With enough technical
knowledge, a robust trading formula and practical pattern recognition
you have a strong basis for a profitable edge. The fact that
traders use different entry techniques, price patterns, technical
indicators or no technical analysis whatsoever means that there
is just enough self fulfilling prophecy present to give technical
analysis profit potential.
Market Psychology and Herd Mentality
Moving away from the idea of the self-fulfilling prophecy is the
analysis of market psychology and herd mentality. Your ability
to read this is an integral part of trading. Technical analysis
is designed to give us a means to define this psychology and
the resultant market action in the form of price or indicator
patterns. We can use these patterns to make a prediction as to
the next likely direction price will adopt. Therefore TA is saying
that herd mentality is predictable to a degree and does repeat
itself with enough accuracy in order to highlight trade opportunities.
A Place for Fundamentals
There is always a place for fundamental analysis in trading, even
if this analysis is as basic as knowing when data will be released.
In just the same way that technical traders react differently
to the same price chart, fundamentalists will react differently
to the same piece of news. Market reaction to fundamental news
can be unpredictable and violent and the resultant price action
will add another variable to the potential success of technical
analysis.
Technical Analysis and Timeframes
Technical analysis can be used on all time frames. The general
consensus is that the most significant price patterns and indicator
set-ups are the ones that occur on the longer time frames, such
as daily or weekly charts. Whether you decide to use short, medium
or long-term time frames will depend on your characteristics
as a trader. However it is always prudent for traders to analyse
all timeframes so they can be aware of the full technical picture.
It is the short-term price action that that paints the long-term
picture and the long-term picture that has a determining effect
on short-term moves.
Implications for Technical
Analysis and Trading Systems
When using technical analysis to design a trading system it should
be remembered that a price pattern is not an ATM machine. Technical
analysts focus on predicting the future using observations of the
past. However it is more effective to see TA as simply a means
to determine entry and exit points. At first glance you may think
that attempting to predict the future and determining entry and
exit points are the same thing, but altering the phrase you use
to describe your objective brings about a profound psychological
change on your part. Predicting the future via the use of past
examples ultimately leads to your prediction being right or wrong.
Not only do we humans hate to be wrong but we hate it even more
when we stake money on it. Without going into too much detail about
trading psychology (we’ll leave this for another article)
almost any emotion whatsoever can have a negative bearing on your
trading. Losing a trade (and money) will make you go back to your
technical analysis book and library of price charts to find out
what on earth went wrong. You will undoubtedly see that the pattern
you used for your entry was slightly different (it always is, we
have already touched on why) and therefore you could have entered
differently or not at all. This is the first stage of doubting
your edge which can lead to all sorts of problems. Now suppose
your pattern was just an entry point: If you have set your risk
and target based on solid money management then you have given
yourself the opportunity to profit from the potential you have
identified, nothing more, nothing less. Now you must wait for an
exit signal or for your target/ risk threshold to be reached. In
effect you are reacting to signals the market gives you or flowing
with the market. You are participating and not anticipating. Therefore
you cannot be right or wrong. Ego, fear and greed will not play
a part in your decisions.
